LED Help (no0b)
I am just getting into building my own electronics/gadgets.
I have decided that my first project is going to be a simple (hopefully) led light that can be toggled on/off via a small push button and most importantly can be toggled on/off when in contact with a metal rod. So, when the led is in contact with the rod, it will turn off, and when not, it will light up.
The power source for the led will be a cr2032 (3 volt) battery.
For a visual, think of those small led lights that you can add to your key chain.
It pretty much the same concept, but if the led was on, and you were to place it on something metal, it would turn off.
I think I can bring my project up to the point of a working led with a push button, but have no idea on how to set it up to turn off when in contact with metal.
Any help would be greatly appreciated.
